(Ittorne i Filed Oct. 18, 1934 6' Giraud Patented Sept. 22, 1936 UNITEDSTATES PATENT OFFIQE VICE FOR LIQUID INGS CONTAINING PIP- Carlo Giraud,Savona, Italy Application October 18, 1934, Serial No. 748,973 ,In ItalyJuly 17, 1934 2 Claims.

This invention relates to a separating, emptying and cleaning device forliquid-containing pipings, particularly pipings of very large diameter.

The device according to this invention comprises a cylindrical brush,composed of cylindrical rings, the terminal ones of which are providedwith a hemispherical or tapering end closure, said rings being providedat their peripheries with tufts of bristles forming a brush and beingconnected by suitable flexible means, such as a coil spring which allowsthem to adjust themselves to the curves of the pipings and to pass overany deformations said brush being adapted to empty the pipings andseparate the liquids contained therein and to clean the pipings duringthe passage of the brush. Of course as regards separation by the brushthe question is of a relative and not complete separation, sufficienthowever to the necessities of many industries.

The invention will now be further described by Way of example withreference to the accompanying drawing in which:

Figure 1 is a view partly in section showing the application of thedevice to a piping;

Figure 2 is a longitudinal section of a cylindrical brush employed inthe device according to the invention;

Figure 3 is an end view of the brush.

The device according to the invention comprises, as shown in thedrawing, the brush unit A illustrated in detail in Figs. 2 and 3 and iscomposed of a series of cylindrical rings I having aligning hubs 2 andhaving tufts of bristles 3 fixed at their peripheries. The two terminalrings 4 and 5 instead of having hubs are provided with convex or taperedwalls 6 on their outer edges which act as end closures for the brushunit. Said rings are connected to one another by any desired means, forinstance by a spring 6 arranged through the aligning hubs 2 and havingthe ends connected to cross pins 1 in the end rings thereby allowing therings to adjust themselves so that the brush may freely run along thecurves of the piping P and pass over any deformations.

From the foregoing it will be observed that owing to the specialconstruction of my improved brush, and particularly the closed end rings4 and 5 thereof, the device may serve as a partition in the piping tosubstantially separate two liquids therein. Of course, it would also benoted my improved brush is particularly adapted to function as anemptying or cleaning device for the piping, by moving the brush withinthe pipe by any suitable means, such as compressed air or the like,whereby the liquid will be forced along in advance of the brush untilsaid liquid reaches an exit from said pipe.

I claim:

1. A device for emptying and cleaning pipes or 15 the like, comprising acylindrical brush composed of a series of cylindrical rings, each ringhaving a central hub arranged in substantial alignment with the hub ofan adjacent ring when the rings are in juxtaposed condition, each endring of said series being provided with an end closure, securing meanson said end rings, tufts of bristles projecting outwardly from theperiphery of each ring, resiliently contractile and flexible meansextending through said hubs and having its ends connected to saidsecuring means for connecting the rings together, whereby said rings mayadjust themselves to the curves of the pipe and pass over anydeformations therein.

2. A device for emptying and eieaning pipes or the like, comprising acylindrical brush composed of a series of cylindrical rings, each ringhaving a central hub arranged in substantial alignment with the hub ofan adjacent ring when the rings are in juxtaposed condition, said ringsnormally abutting each other and forming a substantially compact unitarystructure, each end ring of said series being provided withan endclosure, securing means on said end rings, tufts of bristles projectingoutwardly from the periphery of each ring, resiliently contractile andflexible means extending through said hubs and having its ends connectedto said securing means for connecting the rings together, whereby saidrings may adjust themselves to the curves of the pipe and pass over anydeformations therein.
